According to definitions, in order to obtain essential oils we need to extract the raw material with hydro-distillation. Since my raw material is a seed (with tough seed coat), and since hydro-distillation won't result in high amount of essential oil, I was thinking maybe enzyme pretreatment will be a good idea for optimizing that. But first I wanna make sure if its a suitable pretreatment method.
Looking forward to hear your experiences.
Thank you in advance~
